SCH 4U Chapter 7 Chemical Systems in Equilibrium Equilibrium Calculation Exercise 3 Nelson: Section 7.2, 7.5 1. If K eq for the production of NH 3 (g) is 2.37 x 10 -3 L 2 ∙mol -2 and [N 2 (g) ] = 2.0 mol/L, [H 2 (g) ] = 3.0 mol/L, calculate [NH 3 (g) ]. (0.36mol/L) 2. A reaction vessel with a capacity of 1.0 litre in which the reaction SO 2 (g) + NO 2 (g) ↔ SO 3 (g) + NO (g) had reached a state of equilibrium, was found to contain 0.8 mole of SO 3 (g) , 0.4 mole of NO (g) , and 0.2 mole of NO 2 (g) and 0.4 mole of SO 2 (g) . Calculate the equilibrium constant for the reaction. (4.0) 3. Calculate the K eq for the reaction 2NO (g) + O 2 (g) ↔ 2NO 2 (g) if it is known that at equilibrium in a container of 0.76 litres, there are 0.19 moles of NO 2 (g) , 2.65 x 10 -4 moles of NO (g) and 0.606 moles of O 2 (g) . (6.4 x 10 5 L/mol) 4. The K eq for the following reaction is 3 at 1000°C. 2SO 2(g) + O 2(g) ↔ 2SO 3(g) . An equilibrium system at 1000°C contains 18 moles of SO 3(g)
